Play a DASH stream with Dolby and tunneling.

Have you tried playing this stream without tunneling by any chance? Tunneling moves a lot of the playback logic, AV sync and decoding to a part of the output device that isn't covered by Android tests and reimplemented by every device. This usually causes a lot of compatibility issues and we only recommend tunneling on a device-by-device basis once you tested your streams work on that particular device.

[zubcoco]

So I don't reproduce the problem without tunneling. But I can provide one more piece of information since the ticket was opened: during the 20 seconds when the logs indicate changes to isLoading (true-false), the image is frozen but the sound continues to play. And after these 20 seconds, everything stops. A new seek resets the playback.

[zubcoco]

The problem can easily be reproduced on the media3 sample when enabling tunneling.
However, if we make 5 seconds seeks, the player freezes for a few seconds with the sound and then continues playback.
But with jumps of 10 seconds or more, the player freezes for a few seconds with sound, then stay in buffering state.

[tonihei]

In this case, it unfortunately just sounds like a device-specific issue with the tunneling implementation we can't fix. You'd need to reach out to the device manufacturer and ask them to fix the issue or (more realistically) just disable tunneling on these devices in your app.
